New symptoms in 3rd pregnancy

Every once in a while (couple of weeks or so) I have been really really sore on the surface of my tummy. It's the muscles. It's like the baby gains a few ounces overnight and is suddenly so heavy that I'm sore. After a few days I adjust and it's fine until next time. I'm thinking its growing pains but never had this before. Anyone else?

I have the same thing. Especially if I was more active during the day.
Sometimes the pain of me growing To make room for baby makes me double over and I can't do anything but wait for it to pass.
When was your last pregnancy?
Good luck!
